Each week our friends at Inhabitat recap the week’s most interesting green developments and clean tech news for us — it’s the Week in Green.

Inhabitat is always interested in finding innovative uses for old technology, and this week we saw artists and designers from around the world produce new things from old, unused or outmoded gadgets. In Osaka, a local goldfish club has been transforming old phone booths into gigantic public fish tanks. In another large-scale art installation, Babis Panagiotidis used 18,000 recycled computer keys to make a life-size rocking horse. London artist Leonardo Ulian also makes beautiful, ornate mandalas from bits and pieces of old circuitry. And Benjamin Yates makes his unique coffee tables from recycled circuit boards, old VCRs and computer components.

This is a newly discovered species of Yeti (NOT Batman) crab. It’s similar to the other hairy-armed Yeti crabs except this one grows edible bacteria on its arms by methodically waving them around in front of deep sea methane vents. And speaking of deep sea methane vents: blue whales. You don’t want to be sitting in a dinghy when one of those fart bubbles surfaces!

Hit the jump for two short videos, one of the hairy arm waving, one of chow-time.

Ever thought about upgrading your PC by breeding more cores? Or planting a few GBs of extra storage out in the yard? Us neither, until we heard that scientists at Imperial College in London have succeeded in building “some of the basic components of digital devices” out of genetically modified E.Coli. We’ve seen these germs exploited in a similar way before, but Imperial’s researchers claim they’re the first to make bacterial logic gates that can be fitted together to form more complex gates and potentially whole biological processors. Aside from our strange upgrade fantasies, such processors could one day be implanted into living bodies — to weed out cancer cells, clean arteries and deliver medication exactly where it’s needed. So much for Activia.

You know that movie (go read some IWatchStuff, shit!) ‘Contagion’ coming out tomorrow that I’m not gonna see and will forever make it impossible to Google ‘contagion’ without getting a bunch of movie information first? Well to promote it, Warner Bros. Canada created this “living” billboard by carefully inoculating a giant rectangular petri dish with different bacteria and mold to produce a sign that reads, you guessed it!: CONTAGION. Admittedly, it’s kind of clever. Gross, but clever. Would I still take a bite of it? Not for less than a dollar.

Hit the jump for a worthwhile video of the I think there was some of that on my toast this morning in action.

Few things are quite as exciting as a good old fashioned feud between distinguished scientists. You’ll recall that a scientist, Nasa’s Richard Hoover, published an article last week in The Journal of Cosmology that claimed to have discovered a form of extraterrestrial bacteria on a meteorite. Life, in other words. But hold on! In the days that have since passed a number of scientists have come out agains the claim, saying that the original article was flawed, and, in essence, there’s nothing to see here; move along. What gives?

First, some more background info. The article, Fossils of Cyanobacteria in CI1 Carbonaceous Meteorites, argued that, having found bacteria on certain meteorites, life on Earth “may have come from other planets.” It’s sorta like how Superman crash-landed on Earth: life coming from elsewhere, adjusting to this planet’s climate and eventually thriving.

This, of course, pretty much flies in the face of existing scientific theories about the origin of life on planet Earth, so naturally there was bound to be some opposition.

One such opposer, the University of British Columbia’s Rosie Redfield, said the article was, in essence, a load of bunk, saying that the article may be a lot of things, but it certainly wasn’t science.

A Harvard astronomer, Rudy Schild, said the article, while fun and all, wasn’t properly peer-reviewed. What good is a scientific article if it’s not peer-reviewed? What’s to stop me from writing a post saying I’ve discovered a way to turn old coffee grounds into gold?

The Journal of Cosmology, of course, says that the article was, in fact, peer-reviewed. In fact, it called the article its most reviewed article ever. So go figure.

Does any of this sound familiar? It should. Remember that whole arsenic-using bacteria brouhaha from a few months ago? It’s a similar situation here: scientist makes a grand claim, and other scientists immediately hate on the claim.

As the world turns, I suppose.

Salmonella typhimurium (red) invading cultured human cells If your kids are anything like mine, they are not only inquisitive sorts but they catch on to what’s going on in the world and start to ask questions. Sometimes you have the answers to those questions, sometimes you have to make up the answers (or Google them) and the other times you just shrug, tussle their hair and go back to soldering. However, when the questions are concerning something that possibly might directly affect their lives, you can’t just ignore them. Unless you are a vegan family, your kids probably eat eggs and they are wondering right now if that messy omelet you just let them make is going to put them in the hospital. Thankfully GeekDad is here to answer some of the most common questions. How did the eggs get contaminated in the first place? The egg recall last week, that has since been expanded, has put a lot of egg eaters on edge. About 380 million eggs, or 32 million dozen-egg cartons have been recalled. Hundreds of people have reported being sickened by the eggs thus far in at least three states — there have been no reported deaths. Most likely there are more states that will be reporting sicknesses soon, but they might not have iPhones and have to dial the CDC (Center for Disease Control) the old-fashioned way. So how did this outbreak happen? Irresponsible behavior, that’s how. This is a great lesson in how not to run a business. The outbreak came from Wright County Egg in Galt, Iowa. Wright County Egg is part of the DeCoster family agribusiness operations. The DeCoster family of businesses has a laundry list of safety & operational violations. One of those violations was letting 380 million eggs come into contact with rodents, animal feces and unsanitary hen houses. It was only a matter of time before something big slipped through the cracks. Things just got scrambled. What is the danger if I eat contaminated eggs? This question will come from the daring and the stubborn ones. The ones who challenge the facts and want to know – what’s so bad about eating the eggs? Just throw this word at them – salmonella. I’m pretty sure they’ve heard it before, when handling raw chicken or raw eggs. It’s always a possibility, and is the most common bacterial form of food poisoning. In fact, it leads to about 30 deaths in the annual average 142,000 cases a year. Clearly that’s not a high number compared to the population, but it’s a number nonetheless. Salmonella (Kingdom, Bacteria; Class, Gamma Proteobacteria; Order, Enterobacteriales; Family, Enterobacteriaceae; Genus, Salmonella) will make you sick, and many more people get sick each year than get reported. That number goes up considerably when there is a contaminated product like this batch of eggs. If you want to show your kids one of the worst slide shows ever to illustrate a sickness, check out this one over at CBS.com. It deftly illustrates that salmonella will cause stomach cramps, nausea, unfortunate bowel movements and so on. Basically, your abdomen wants to expel the germs as much as possible so it makes your abdomen contract over and over, which causes the cramps and stomach sickness. Basically, there is no way for your child to fake salmonella poisoning to get out of going back to school. If your child is sick, you’ll know it and so will they. If they aren’t old enough to be forced to drink, the emergency room is in your immediate future as you don’t want dehydration to set in. Here’s the rub though, and the smart ones might figure this out: If you cook infected eggs you will kill the bacteria. Cooking eggs to the temperature of 72°Celsius/160°Fahrenheit is all you need to kill the bacteria. Of course, you still run a risk if you under cook the eggs. So really, if you have a two dollar carton of eggs in the fridge you have two choices, cook them anyway and save yourself two bucks, or throw them out. Well, three choices, you can draw targets on the fence and you and the kids can have target practice. Just sayin’. So what came first? The Chicken or the egg? The egg. Because dinosaurs laid eggs. And dinosaurs came before chickens. So there. How do I know if my eggs are bad? That’s the easy part: Check out this handy list to see if your carton number is on there. Have the kids do a little number comparison and see if they can find a pattern. Of course, the article gives away the range, but perhaps there is something deeper in the numbers. If you can figure it out, leave it in the comments. Of course, I might just be making it up – but I’m sure you’ll come up with something. You awesome geeks always do.

Each week our friends at Inhabitat recap the week’s most interesting green developments and clean tech news for us — it’s the Week in Green.

This week Inhabitat showcased the best and brightest new developments from the world of clean tech. Stanford opened up new horizons for renewable energy as they unveiled a solar technology that can harvest electricity from both heat and light — a significant improvement over photovoltaics, whose efficiency wilts in the sun. We also looked at Pocono Raceway, the recently-crowned world’s largest solar-powered sports facility, and an innovative new type of “Wind Lens” turbine that could increase energy generation by a magnitude of three times.

We also saw green tech take to the skies as Boeing unveiled a super-efficient airplane that could cut fuel consumption by 70% and scientists floated a plan to create gigantic orbiting balloons that could solve our space junk problem. It was a big week for alternative autos as well — Paris announced that it will be launching its Autolib electric car sharing program next year, and a poo-powered VW Bug burned… rubber on the streets of Bristol.

In other news, we showcased an ultra-efficient Danish home that produces more energy than it needs. Future-forward biotech couture was a hot topic as well as scientists found a way to produce spider silk from metabolically engineered bacteria. And we couldn’t help but want to share these adorable and amazingly detailed little LEGO CubeDudes created by PIXAR animator Angus MacLane.

We recently checked out the Game Gripper, which quickly turns a Motorola Droid keyboard into a gamepad, and when it comes to simplicity and cost it doesn’t get much better than that. But, it isn’t quite the same as a real controller, not not like this creation from Bacteria, creator of many a wonderfully hacked console. Here he took an MSI BGP100 Bluetooth GamePad and stuffed it into a classic SNES controller shell, enabling all the buttons except, sadly, the lowly Select. It’s all demonstrated in a thrilling video after the break that features action, gameplay, and nearly a minute of screw-turning excitement. The best part? He was hired to do this, meaning if you ask nicely (and write a check) he might just make one for you, too.
